If someone posts content straight to the wiki rather than in discussion, that's fine as long as they are satisfied being subjected to group editing.

I would prefer not to have to go through and audit the wiki to make sure I can endorse the page every time I make a link to earlier lesswrong work. Quite frankly I would prefer not to have a wiki at all. Then the blog posts themselves can be referred to instead, serving most of the same purposes even though it isn't quite as convenient.
